derivative of an ecuation

[IñigoP]

Hello to everyone,

Is there a way to calculate the derivative of a polynomial? I attached the way I calculate the polynomial. Also I want to evaluate the derivated ecuation in Y equal to zero to obtain the maximum of the polynomial equation of order 2.

Thank you in advance.

Hi Inigo,

simple math: the derivative of a polynomial sum(a_i × x^i) is sum(i × a_i × x^(i-1) ).

 (Using Word: )

You get the polynomial coefficients a_i from that function!

have you tried "nth derivative of polynomial.vi" ?
